STEAM REGENERATIVE ACCUMULATOR.

To all whom it may concern:

. Be it known that I, EMIL ECKMANN, a citizen of the German Empire,residing at Neubeckum, in the Province of \Vestfalia and Kingdom ofPrussia, Germany, have invented certain new and useful Improvements inSteam Regenerative Accumulators; and I do hereby declare the followingto be a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which it appertains to make anduse the same.

One form of apparatus according to the present invention is illustrated,by way of example, in the accompanying drawing, in which Figure 1 is alongitudinal section of the accumulator, Fig. 2 a cross-section of thesame on the line AA of Fig. l, and Fig. 3 a cross-section on the line BBof Fig. 1. Fig. 4 shows to an enlarged scale the waterlevel regulator invertical section, and Fig. 5 a regulating valve in vertical section.

In the shell a of the accumulator a troughshaped channel 6 Z) is formed,the bottom (Z of which is open at both ends and thus constituting adeflector for the current of water and steam in said water space. Theupper wall or partition 0 or roof of the channel and water space risessomewhat behind and is open at the back end. It separates thewater-space of the accumulator from the steam-space of the same. At thefront end in a vertical wall m two shovel-shaped steam inlet passages fare pivotally supported at a,

into the wide back openings of which the steam is introduced through thepipes 11.. The tight fit of the passages f in the wall on as well as thelatter itself prevent the steam rom passing directly from the passages fbackward into the steam-space. The front ends of the passages f openbelow the wall 0 into the water-space and are adjustable in height bymeans of the hand-wheel g and spindle it, so that the steam can becaused to enter as desired more or less below the water-level in orderto cause it to overcome more or less resistance in the water for thepurpose of regulating the pressure of the steam. A wall at connectedwit-h the passages fits during the height-adjustment of the passagesagainst the wall 0 and prevents the passage of steam at this place intothe steamspace.

In the upper wall 0 of the trough-shaped channel there are providedvalve-like outlet- Specification of Letters Patent.

devices 2' one behind the other, which devices according to requirementsooner or later give an outlet into the steam accumulating space to thesteam bubbles in the water space and consequently serve to regulate thesteam pressure, the outlet opening at each device 2' being greater orless according to its adjustment below stated. According to theconstruction illustrated, particularly by Fig. 5, each of these valvesconsists of a short casing 2' open above and connected with the wall 0,in which casing a substantially funnel-shaped valve seat 0 is arranged,and of an umbrella-like valve-body p which by means of a screwed spindleQ' is so guided in a bridge 1' secured on the casing 2' that it can beadjustable in height. The adjustment of the outlet valves '5 must in thecase of the form shown be effected from the interior of the apparatusbefore the commencement of the running of the plant. If these valves beadjusted say as in Fig. 5 they will let the steam pass from the channel5 b as rapidly as it comes into said channel, but if the steam come inlarge quantities under pressure and therefore goes out through thedevices 2' in irregular amounts instead of in a steady volume this evilmay be corrected by adjusting the valve 3) nearer the valve-seat 0according to the amount of steam being introduced into the channel 0 Z).Of course this may oftentimes be judged or ascertained from the style ofengine from which it is to receive exhaust steam. The water-level in theaccumulator is always kept at such a height with the aid of a suitableregulating device that the steam bubbles cannot pass into thesteam-space along a path other than that through the outlet-valves 2'.From said steam space the steam ascends into a steam-dome 7a and passesthence through an outlet. tube Z to the motor. In the exampleillustrated, this regulating device consists of a vertical cylindricalreceptacle 8 which is connected by means of the unions 2 u with thewaterspace and the steam-space of the accumulator. In the receptacle 8 afloat o is guided so as to be capable of moving vertically, the lowerguide-rod of which is connected with a valve to while the upper guiderodcarries an adjustable load 00. If the water-level in the accumulatormounts too high, then the float 'v in the receptacle communicating withthe accumulator is raised and the valve to thereby opened, so that waterflows away until the water-level reaches its normal height and until thefloat has closed the valve.

The union 2? is connected with a fairly long pipe t which runshorizontally inside the accumulator and the end of which is situated ina zone of the accumulator in which the flow of the water is less violentthan at the back end of the bottom of the accumulator, so that violentfluctuations in the water-level regulator are avoided. A closable uniony arranged at the back end of the accumulator at the deepest part of thesame serves to empty the accumulator.

The steam is led to the secondary machine through the pipe Z connectedto the steamdome L.

What I claim as my invention and desire to secure by Letters Patentis 1. An accumulator shell for steam regenerators having its interiordivided into a water space and a steam space by the top of the former,said spaces communicating at one point only, in combination with valvesin said top which may be opened when the pressure of the steam belowthem reaches a certain degree, means for supplying steam to the watercompartment and means for regulating the depth below the surface of thepoint of such supply for the purpose set forth.

2. An accumulator having water and steam spaces and means for permittingthe passage of steam from the latter to the former valves openingadditional passages between them, means for supplying steam to saidwater space and a deflecting plate arranged in said water space anddividing it into parts but permitting the passage of water around itsends.

3. In combination with an accumulator shell and a deflecting platearranged within the same and providing water passages at both ends, apartition dividing the interior of said shell into awater spacecontaining said deflector and an upper steam space, means for supplyingsteam to said water space, means for permitting steam under pressure toescape from said water space to said steam space and. means forregulating the water-level, said regulating means being in connectionwith said steam space, and comprising a tube adapted to admit water andextending far under said deflector to a point where the water is lessagitated than at the ends of the water space.

4. An accumulator comprising a waterspace, a steam-space and means ofcommunication between them, in combination with a steam pipe, a taperinginlet passage receiv ing said steam and having an adjustable inner endfor discharging it into said water space and means for adjusting saidend of the passage to vary the depth at which the steam therefrom willenter the water and the degree of resistance encountered substantiallyas set forth.

5. An accumulator provided with a waterspace, in combination with adouble channel arranged within the same, a pair of steam inlet passagesdischarging into the water space above said channel and having theirinner ends vertically adjustable and means for supplying steam to saidinlet passages substantially as set forth.

6. An elongated horizontal accumulator shell, in combination with asteam dome and outlet pipe above the same, a partition dividing theinterior of said shell into a steam space communicating with said domeand a water space below said steam space, valves making communicationbetween said spaces, means for adjusting said valves, adjustable meansfor supplying steam to said water space, a water-level regulatorconnected to both spaces and a deflector arranged in said water spacebut having water passages at each end substantially as set forth.

In testimony whereof, I have signed my name to this specification in thepresence of two subscribing witnesses.
